Enum Constant Summary

Enum Constants

Enum Constant and Description
DIST_COUNT 为一次抽取的document数量，默认值为1。
DIST_FILTER 为过滤条件，被过滤的doc不参与distinct，只在后面的 排序中，这些被过滤的doc将和被distinct出来的第一组doc一起参与排序。默认是全部参与distinct。
DIST_TIMES 为抽取的次数，默认值为1。
GRADE 指定档位划分阈值。
KEY 为用户用于做distinct抽取的字段，该字段要求为可过滤字段。
RESERVED 为是否保留抽取之后剩余的结果，true为保留，false则丢弃，丢弃时totalHits的个数会减去被distinct而丢弃的个数，但这个结果不一定准确，默认为true。
UPDATE_TOTAL_HIT 当reserved为false时，设置update_total_hit为true，则最终total_hit会减去被distinct丢弃的的数目（不一定准确），为false则不减； 默认为false。

KEY

public static final Distinct._Fields KEY

为用户用于做distinct抽取的字段，该字段要求为可过滤字段。

DIST_COUNT

public static final Distinct._Fields DIST_COUNT

为一次抽取的document数量，默认值为1。

DIST_TIMES

public static final Distinct._Fields DIST_TIMES

为抽取的次数，默认值为1。

RESERVED

public static final Distinct._Fields RESERVED

为是否保留抽取之后剩余的结果，true为保留，false则丢弃，丢弃时totalHits的个数会减去被distinct而丢弃的个数，但这个结果不一定准确，默认为true。

DIST_FILTER

public static final Distinct._Fields DIST_FILTER

为过滤条件，被过滤的doc不参与distinct，只在后面的 排序中，这些被过滤的doc将和被distinct出来的第一组doc一起参与排序。默认是全部参与distinct。

UPDATE_TOTAL_HIT

public static final Distinct._Fields UPDATE_TOTAL_HIT

当reserved为false时，设置update_total_hit为true，则最终total_hit会减去被distinct丢弃的的数目（不一定准确），为false则不减； 默认为false。

GRADE

public static final Distinct._Fields GRADE

指定档位划分阈值。

Method Detail

values

public static Distinct._Fields[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Distinct._Fields c : Distinct._Fields.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static Distinct._Fields valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
